To all whom it may concern:

lie it known that 1, Jones Bnnnzmorzn, a subject of the Emperor of Germany, residing at New York, in the county of New York and State of New York, have invented certain new 'and useful Improvements in Can-Heading Machines, of which the following is a specification.

My invention relates to can heading machines and more particularly to double-seeming machines and its object is to provide a machine in which greater rapidity of operation with the same power as that employed by other machines of this class, is obtained, and in which the seaming rollers are carried by a pattern following carriage of simple xrfovernent and strong construction. 7 '7 My invention relates particularly to machines for bending square and irregularly shaped cans.

To this end my invention comprises the elements and combinations particularly hereinafter described and pointed out in the claims.

In its preferred embodiment my invention is illustrated in the accompanying drawings, in which Figure l is a. front view in elevation of the machine; Fig. 2, a side view; Fig. 3, a. horizontal section on line 3-4: of Fig. 1; Fig. 4, a detail view of the forming roller and can seam; Fig. 5, a similar view of the locking roller; Fig. 6, a vertical section of the roller supporting means; Fig. 7, a detail plan of the roller-slide; Fig. 8, a transverse vertical section in line yy oi Fig. :6; Fig. 9, a horizontal section of the clutch; Fig. 10, a s ction of clutch operating means, and Fig. 11, 9. rear do tail view in elevation showing the can locking and con trolling mechanism and Fig. 12, a dctail vertical sectlon on reduced scale of clutch-cam.

Referring to the drawings, 1 is the table on which a can to be headed is placed. This table is provided with a raised can-holding plate 2 on its upper surface to receive the end of a can. The inblc is swiveled in a horizontal frame 3 fixed at the upper end of a vertically slidsble shaft 4 mounted in 9.1'1118'5 extend ing from the main frame 6. To this shaft 4 is fixed between the 'arms 5 a frame 7, to which is connected links 8, one on catch side of the shaft. The upper ends of links 8 are pivoted to the inner ends of a lurked lever 9 pivoted at 10 to the upper one of the arms 5, and having an operating handle ll whereby the frame 7, shalt 4 and table I kll'l' raised when the handle is depressed so as to present the can l?! roper position for the heading operation Pivoted to the end oi .mmm 12 depending from the forked lever 9 is 1|. rod 31% secured at its rear end to a swinging frame 14 pivotnily hung on a pin 15 fixed in See Figs. 2 and 11. This swinging frame 14 has a slot 16 in which is journaled a. roller 17,

adapted to engage a recess 18 in a roller or cam 19 mounted on a shaft 20 journaled in the frame, whereby when the roller 17 falls into said recess the clutch mech anism connecting with said frame is released and the machine is stopped. The shaft 2 0 is provided with a beveled gear wheel 21 driven by a miter wheel 22 on a. vertical shaft 23 connected with the driving mechanism as hereinafter described.

To the upper end of rocking frame 14 is fixed an arm 24 to which is pivoted the lower end of a. rod 25 having its upper part provided with an adjustable nut 26 adapted to bear against 9. collar 27 extending from the end of a lever 28 pivoted by a pin and slot conncction 29 to s. non-rotating cam 30 mounted to slide vertically on a She-ft 31 carrying a lower section of a main driving pulley whose upper part 32 is adapted to be connected to the lower section by a friction clutch and around the periphery of which upper section is run a muin driving belt 33 running over pulleys 34 and over driving pulley 35 on shaft 36 which is provided with pulleys 37 adapted to be connected with any suitable driving belt.

The clutch mechanism (see Figs. 9 and 10) comprises shoes 38 secured to hinged arms 39 to which are pivoted toggle-lovers 40 pivoted at their opposite ends to a slide 41 having a roller 42 which cngngos and rides upon com 30 whereby the toggle-levers are actuated by the slide to draw the clutch shoes away from the inner periphery of pulley section 32, and which roller is also engaged and pressed lay an arm 43 pivoted to the under suriuce oi the pulley section and having its free endnttsched to n coiled spring 44 whereby the slide and its toggle aims are forced hock so as to carry outward the brake shoes against the inner surface of the pulley and connect the letter with the driving shafts. As the roller 42 is rcvolv'cd with lower pulley section by its bearing on the high part oi the cam, these shoes will he held away from the pulley section 32 and when the low part of cam is reached the roller will be withdrawn and the clutch shoes applied. The upper edge portion of the cum has a plain perimeter 45, whereby the roller will not contact with the corn except when the latter is raised whiz-his effected lay a return spring 46 secured at one end to the main frame work and at the other end to the end of a rocking lever 47 i The levers 47 and 28 are connected by a rod 48 pivoted to each lever. By this connection lmlh lovers are returned by spring 46. The lever 47 is pivoted at 49 to the frame and provided will! u ffll'lild end engagiugn pin carried by a slide piece 50 to which is secured a. brake-shoe 51 adapted to make contact with a wheel 52 mounted on the upper end of the shaft 31. This brake serves to revent the further rotation of the clutch and other meehanisms by momentum after the driving connection has been unelntehed. The advantage of applying such momentum brake to the clutch shaft is that only the weight. of the eluteh amt other connected seaming parts opposes its momentum to the force of the brake.

Within shaft Ill is fixed a shalt 53, journaled in a hearing 54 extending from the t'ramework aml earrying at its lower end a. gear wheel 55 to whit-h is fixed a pattern cam 5t) having: an interior out out design eort'espending to the shape of the eau to be headed and provided with a eentral depending ehnt-k 57. The ehnek 57 is provided nith a groove 58 and an annular tlange 59. With this ehuek is adapted to eot'iperate in order to head the (an a pair of forming rolls lit) aml an oppo Bite pair of locking rolls til, eaeh provided with seaming collars and grooves. The rollers are mounted so as to oscillate on a eommon eenter andby these means it is possible. to provide t\\'tl forming rollers and two loeking rollers, whereby greater rapidity of operation is obtained with the same atnount of power.

The rollers 01' (tltll pair are journaled in a slide 02, whereby they may be t-arried against the uni head into position to roll the seam. The slide n2 is pro vided with side grooves tilt adapted to engage a rail tt-l of rotary earriage 5 having a eentral disk head tilt adapted to be rotatably seated upon a shoulder I57 ot' a guide plate H8 whit-h is rigidly tixed to the frame work. lly these means the earriage tt-i is free to oseillate in the guide plate oh. This oseillatine movement is I tlTOt'lUtl and eontrolled by pattern rollers till journaled in the earriage H5 and entering and bearing against the inner wall of the pattern eam Fiti so as to be eontrolled intheir movement thereby.

The slide ti! lits into the bottom ot earriage t' 5 aml is provided with a pin Til to \\'lllt'll is pivoted the end of a toggle-arm Tl. housed in the ear and slide. The opposite end of the toggle-arm Tl is lorlted amt pi\oted \vhieh has its opposite end to another toggle-arm is. pivoted toa blot-k Tit atljustably fixed intheearriagettiw.

An aetuatinp toggle rod T t is pivoted to the pin joining arms 7t and 7-, and by meant-tot the vertieal reeiprotation of this rod the toggle lever is aetuated to slide the seaming rollers in and out. This rod is provided with two t'ollars 7 between \\'lll('ll loosely extends the forked end It; of a l'tit'klllg lever TT by \rhieh the rod is operated. The other end 78 ot' the lever is similarly formed and extends between two eollars 7t) fixed-on a vertieally sliding rod h'tl mounted in the frame aml pro vided at its lower end with a roller 8| hearing on and netuated by a eam H2 llxed on the shaft 2t)v 'loa pin tstt extending from the upper one of the two eollars 79 is attaehed the upper end of a (oiled return spring 84 having its lower end fastened to a lixed part. of the framework This spring n-ves to pull down the rod 80' and end of roeking lever 77 after the lattorhave been aetuated by the ram 82. A pin 85 extends from the lower part. of rod St) and entzages a slot. 86 in a plate extending from the frame whereby any undue upward throw of the rod by the eam is prevented. v

The earns H2 are set. in a dvanee one of the other in order that the forming rollers may he slid inward against the ean seam first and be followed by the loekinp rollors Wlll('ll will engage the seam as the forming rollers are withdrawn therefrom. lloth pairs of rollers are probeen interloeked and bent down, whereupon the low vided with adjusting means to permit. their relative distance from the ehuek to he regulated as desired to aeeommodate eans of varying thiekness or to take up distant-es for wear and tear. These adjusting means consist of a eontaet serew 8? extending from block 73 through a bar 88, supported on said serew and on other serews St) extending from the earriage (t5 whieh are provided with nuts by 'ltlt'lt the bloek 73 and its eonneeted slide ti2 may be adjusted in and out relative to the rotary earriage and the ehnek.

The adjustment means for the loekin" ollers slide is provided with a yielding butter Flt) eoni}. vedoi rubber rings or springs, seated between two eollars [t] on screw H7 extending from block 73. lly means of this buffer the slide and locking rollers will yield to pass any unevenness and the side seam of the can. The buffer is unneeessary for the forming rollers and its slide.

The van supporting table 1 is rotated positively and synehrononsly with the ehuek and to this end its gear wheel is in mesh with a gear 92 on the frame 3, which gear in turn engages wheel 93, also mounted on frame it. and provided with slid-able vertieal pins 9-1 extending through a. eolla r 5 5 lixed on a vertieal shaft 96 whieh is provided at its upper end with a gear wheel 97 meshing with gear wheel 98 engaging wheel 55 on the pattern ram and tixed to the vertieal driving shaft 53. By the gear eouneetion the van supporting table is rotated positively and s \'nehronousl v with the ehnek The shaft llti is provided With a pinion I00 engaging an intermediate gear whet-l lt l whieh drives-a. gear wheel [02 fixed on the upper end of shaft 22% and thus shaft 20 and its slide aetnat in (anus are driven The operation of the maehine is as follows? A ean is plat-ed on the table I and the handle It then depressed \rhieh res frame 7 am] shaft 4 and upper frame 3 thus raising the table l and also the gears 92. 93. The can head is thus brought against and under the ehut'k 57. Sitnultam-tmsly with the raising of the table the dopression of the handle \vill through its frame. push rod l3 baeluvard so as to swin the frame it baehward and thereby withdraw the roller I? from the reeess in the lam lt soas to permit shaft 20 to start eats ll) The frame It when roeked moves upward the rod 35 \vhieh rot-ks lever 28 so as to n'ithd aw the eam ill) from the roller 42 and permit the eluteh-shoes to be sprung against the pulley It. and thus eluteh the driving pulley to the driving shat't ill. At. the same time eonneetin rod 48 roeks the lever 47 so as to withdraw the brake from the upper wheel 52. The shaft 53 is thereby driven, rotating pattern eain 5G and ehuck 57 and rt tating table 1 through gears 97, 98. and also cam shat't' 20 through the series of eonnected gears between the shafts 53 and 20. As the shaft 20 rotates therein 82 of the forming rollers will first be actuated to raise the rod tilt and roek the lever 77 so as to actuate the togglearms It and 72 and (any the forming rollers in against the ean and head seam to cooperate with the ehuek. These rollers are held against the seam by the high part of their eam until the flanges of the head and body have 1 25 part of the (am is reaehed by the roller rod and the rollers withdrawn, whereupon the opposing lot-king rollers are then advanced to position by their ram and the seam locketh With the ordinary seaming machine in which a singlc forming roller and a single locking-roller are 0m ployed, it is necessary in order 1,0 obtain a, properly tight joint thal. the chuck be given at lvast twelve rcv0- luliuna With my invention in which Lwn forming and two locking rollers are employed it is llklllly m ni nary to rotate Lhu ehuck six Limos in order to ohlnin Llusame result as with the single mill-r mavhinv, hvncn grvntvr rapidity of operation willi thv snme powur is nhlnined.
